1) only go for the boss when it's close to you.. the best time for this is when she dashes on the ground, jump and pogo nail here using the height from the nail hit to run away

2) stay at the edge. If hornet dashs from the other side it takes 2 dashs and if she throws her nail from the other side it can't hit you.

3) walls are a good way to get away when the spike traps are on the floor but when in the air you are easy to hit.

4) heal when you can. This works when she throws her nail or dashs from the ground just make sure it's from the edge

5) get rid of the spikes when you can THEY WILL MISS YOU UP (unless that's just a me thing) you can hit them with the nail or spells to remove them. Just make them your 2nd priority and dodging being your 1st.
